annoverare-r IN oar-STAMP FEEDERS.

Specification forming part of Letters Patent No. 144,714, dated November 18, 1873 application filed September 2, 1873.

To all whom it may concern:

Be it known that I, J AMEs TULLocK, of Jamestown, Tuolumne county, State vof California, have invented a Feeder for Crushing- Mills 5 andI do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to l make and use my said invention or improveall trouble by the sticking of damp or wet ore is avoided.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is an elevation of my feeder in perspective.

A is an ore-hopper supported by a suitable frame-work. Beneath this hopper is the tray B, which receives the ore from the hopper as fast as may be desired, a suitable regulatinggate being employed. The tray B is inclined as much as may be desired, and is suspended by the links C from the frame O, so that it can receive an oscillating motion forward and back. Beneath the tray a rock-shaft, D, crosses the frame transversely, and an arm, E, eX- tends upward, and is secured by a pin passing through the lugs F on the bottom of the tray and through the slotted upper end of the arm E. The end of the shaft D has a crank, G, formed upon it, and from this crank the rod H connects with one end of a lever-arm, I. This lever is pivotcd near its middle to the frame,

and the other end extends to 'a point near the stampstem J. An adjustable collar, K, is secured to the stem J, and whenever the stamp falls this collar will strike the end of the lever, and through the connecting-rod H the rockshaft will be operated so as to draw the tray back. When the stamp is .again raised, the tray will be allowed to swing forward until the lugs F strike a bar or post, L, which will abruptly stop the tray, and thus tend to loosen and throw forward its contents, this feature being especially valuable when the ore is wet. A spring, M, may be employed behind the tray to assist its forward motion, and a spring,

N, can be employed beneath the end of the lei ver I, but ordinarily the force of gravitation will be sulflcient to operate these parts.

If desired, a spring, P, can be placed upon the end of the lever which is struck by the collar K, so as to relieve the strain and trans mit the force gradually. Suitable adjustingscrews, to regulate the movements of the different parts and the amount of ore beneath the stamp, will regulate the amount fed.

Having thus described my invention, what I claim, and desire to secure by Letters Patent is- 17. The oscillating tray B, supported by the links C, and operated by the shaft D, with its rocker-arm E and crank Gr, together with the lever I, the whole operated from the stem J by means of the adjustable collar K, substantially as and for the purpose described.

2. In combination with the oscillating tray B, operated as herein shown, the post or bar L for giving a concussive or abrupt stop to the tray, substantially as and for the purpose described.

In witness whereof I hereunto set my hand and seal.
